The new UUID can reasonably be considered unique among +all UUIDs created on the local system, +and among UUIDs created on other systems in the past +and in the future. +.PP +There are two types of UUID's which +.B uuidgen +can generate: time-based UUID's and random-based UUID's. By +default +.B uuidgen +will generate a random-based UUID if a high-quality random number +generator is present. Otherwise, it will chose a time-based UUID. It +is possible to force the generation of one of these two +UUID types by using the +.B \-r +or +.B \-t +options. +.SH OPTIONS +.TP +.B \-r +Generate a random-based UUID. This method creates a UUID consisting mostly +of random bits. It requires that the operating system have a high +quality random number generator, such as +.IR /dev/random . +.TP +.B \-t +Generate a time-based UUID. This method creates a UUID based on the system +clock plus the system's ethernet hardware address, if present. +.SH "CONFORMING TO" +OSF DCE 1.1 +.SH AUTHOR +.B uuidgen +was written by Andreas Dilger for libuuid. +.SH AVAILABILITY +The uuidgen command is part of the util-linux-ng package and is available from +ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/. +.SH "SEE ALSO" +.BR libuuid (3) |
